A closed-loop controller using real-time ultrasound flow measurement regulates spinal cord blood flow after spinal cord injury by adjusting norepinephrine infusion to target a predefined flow level.
- Why it matters: Current care mainly controls arterial pressure indirectly, limiting direct tailoring of drug delivery to injured spinal tissue perfusion.
- What they did: The team characterized how vasopressor infusion, arterial pressure, and spinal cord blood flow relate dynamically, then designed feedback control and tested it in simulations, real-time rodents, and pigs.
- The result: In a rodent survival model, feedback control reduced blood flow deviations and variability versus constant dosing and supported functional recovery, supporting translation toward acute spinal cord injury management.
